BACKGROUND

1. Field

The following description relates to high intensity focused ultrasound (HIFU) probes and methods of manufacturing and operating the same.

2. Description of Related Art

Therapeutic devices for diagnosis and treatment of diseases may be classified as invasive devices and non-invasive devices. Ultrasound probes are one of the non-invasive devices. The ultrasound probes may include diagnostic ultrasound transducers and/or therapeutic ultrasound transducers. High intensity focused ultrasound (HIFU) probes are widely used as therapeutic ultrasound probes. Single plane or bi-plane ultrasound images may be obtained by using the HIFU probes.

However, since currently known HIFU probes are fixed types, the single plane or bi-plane ultrasound images may be obtained only from a certain position and a certain direction by using the currently known HIFU probes. Therefore, it is difficult to increase an accuracy of diagnosis and treatment, and consequently, the diagnosis and treatment may be limited.

Hereinafter, an ultrasound probe will be described in detail with reference to the attached drawings. In the drawings, thicknesses of layers and regions are exaggerated for clarity.

FIG. 1 is a front view illustrating an example of an ultrasound probe 10. FIG. 1 is a front view; in other words, a view taken from a direction in which ultrasound is emitted from the ultrasound probe 10. This applies to FIGS. 2 through 6.

Referring to FIG. 1, the ultrasound probe 10 (hereinafter, a first probe 10) includes a first ultrasound transducer 12 and a second ultrasound transducer 16. The first ultrasound transducer 12 may have a circular shape. However, the shape of the first ultrasound transducer 12 may be different. The first ultrasound transducer 12 may be rotated. The first ultrasound transducer 12 is a therapeutic transducer that may be a high intensity focused ultrasound (HIFU) transducer. The first ultrasound transducer 12 includes a slot 14. The slot 14 has a predetermined width W1 and a predetermined length L1. The width W1 of the slot 14 may have a size such that an emission of ultrasound from the second ultrasound transducer 16 may not be interfered. The slot 14 may be formed along a diameter of the first ultrasound transducer 12. Also, the slot 14 may be formed in parallel to the diameter of the first ultrasound transducer 12. The length L1 of the slot 14 is shorter than the diameter of the first ultrasound transducer 12.

The second ultrasound transducer 16 is positioned inside the slot 14. The second ultrasound transducer 16 may be moved along the slot 14. The second ultrasound transducer 16 is a diagnostic transducer. Ultrasound images may be obtained from various positions, for example, from a left side, a center, or a right side of the slot 14, by using the second ultrasound transducer 16. In addition, since the first ultrasound transducer 12 is rotatable, a treatment area, that is, an affected part, may be diagnosed from various positions and directions, whereby improving an accuracy of the diagnosis. Thus, as the accuracy of the diagnosis improves, an accuracy of treatment may also improve.

FIG. 2 is a front view illustrating another example of an ultrasound probe 20. Referring to FIG. 2, the ultrasound probe 20 (hereinafter, a second probe 20) includes a third ultrasound transducer 22, a fourth ultrasound transducer 26, and a fifth ultrasound transducer 28. The third ultrasound transducer 22 is a therapeutic transducer that may be a HIFU transducer. The third ultrasound transducer 22 may be rotated to a right or left side of the third ultrasound transducer 22. An outer appearance of the third ultrasound transducer 22 may be the same as that of the first ultrasound transducer 12 of FIG. 1. The third ultrasound transducer 22 includes a slot 24 of two directions. The slot 24 includes a vertical component and a horizontal component. The vertical and horizontal components of the slot 24 are formed from a center of the third ultrasound transducer 22 toward respective edges thereof.

Since the second probe 20 includes the two movable diagnostic fourth and fifth ultrasound transducers 26 and 28, bi-plane ultrasound images may be obtained from various positions and directions by using the fourth and fifth ultrasound transducers 26 and 28. Owing to the rotation of the third ultrasound transducer 22 and the movability of the fourth and fifth ultrasound transducers 26 and 28, an accuracy of diagnosis and treatment of the second probe 20 may be substantially increased compared to the conventional art, and may be higher than that of the first probe 10 of FIG. 1. Also, accurate diagnosis and monitoring of disease may be possible in real time from various positions and directions.

FIG. 3 is a front view illustrating still another example of an ultrasound probe 30. Referring to FIG. 3, the ultrasound probe 30 (hereinafter, a third probe 30) includes a sixth ultrasound transducer 32, a seventh ultrasound transducer 36, and an eighth ultrasound transducer 38. The sixth ultrasound transducer 32 is a therapeutic transducer that may be a HIFU transducer. Although an outer appearance of the sixth ultrasound transducer 32 is a circular shape, the shape may be different. The sixth ultrasound transducer 32 may be rotated clockwise or counterclockwise. The sixth ultrasound transducer 32 includes a first slot 34A and a second slot 34B. The first and second slots 34A and 34B are connected to form a single slot as shown in FIG. 3, but the first and second slots 34A and 34B may be separated from each other. For example, the second slot 34B may be spaced apart from the first slot 34A. The first slot 34A that is a horizontally-formed slot may be the same as or similar to the slot 14 of FIG. 1. For example, a width and a length of the first slot 34A may be the same as or similar to those of the slot 14 of FIG. 1. The second slot 34B may be perpendicular to the first slot 34A. The second slot 34B is formed from a center of the sixth ultrasound transducer 32 toward an edge (a radiation direction) thereof. A length of the second slot 34B is shorter than a radius (a circular radius as viewed from the front view) of the sixth ultrasound transducer 32. A width and the length of the second slot 34B may be the same as or similar to those of the vertical component of the slot 24 of FIG. 2.

The seventh and eighth ultrasound transducers 36 and 38 are diagnostic transducers. The seventh ultrasound transducer 36 is positioned in the first slot 34A and moved along the first slot 34A.

The seventeenth and eighteenth ultrasound transducers 68 and 69 are respectively provided in the seventh and eighth slots 64B and 64C, and respectively moved along the seventh and eighth slots 64B and 64C.

As described in the examples of FIGS. 1 through 6, an ultrasound probe includes a therapeutic ultrasound transducer that may include a single slot, or two or more slots. Each slot includes a diagnostic ultrasound transducer. Also, the therapeutic ultrasound transducer may further include a through hole. As will be understood from the examples of FIGS. 1 through 6, since one or more slots may be disposed in various ways, the slots may be disposed in various combinations in addition to those described in FIGS. 1 through 6. This means that diagnostic ultrasound transducers may be provided in various ways besides the above-described examples.

FIG. 7 is a cross-sectional view illustrating an example of the sixth probe 60 that is taken along a line 7-7′ of FIG. 6. Referring to FIG. 7, the fifteenth ultrasound transducer 62 includes a concave-curved surface having a predetermined radius. Considering ultrasound focusing on an affected part or a treatment area, the curved surface of the fifteenth therapeutic ultrasound transducer 62 may be, for example, a paraboloid. The sixth slot 64A may also have the same curvature as that of the surface of the fifteenth ultrasound transducer 62. Since the sixteenth ultrasound transducer 66 in the sixth slot 64A may be moved along the sixth slot 64A, the sixteenth ultrasound transducer 66 may be moved while maintaining the same curvature as that of the surface of the fifteenth ultrasound transducer 62. This example may also be applied to the examples illustrated in FIGS. 1 through 5.

A method of manufacturing an ultrasound probe will now be described. As shown in FIGS. 1 through 6, a single slot or a plurality of slots may be formed in a therapeutic ultrasound transducer. The therapeutic ultrasound transducer may be coupled to a single diagnostic ultrasound transducer or a plurality of diagnostic ultrasound transducers in such a way that the diagnostic ultrasound transducers are formed and movable in respective slots. In the manufacturing method, as shown in FIGS. 1 through 6, the slots may be formed in various shapes and may be separated from each other, and as shown in FIG. 5, the through hole 56 is formed in the center of the therapeutic twelfth ultrasound transducer 52 and spaced apart from the fifth slot 54, and the thirteenth ultrasound transducer 58 is formed in the through hole 56.

A method of operating an ultrasound probe will now be described. For example, the third probe 30 illustrated in FIG. 3 (e.g., a processor of the third probe 30) may initially obtain a bi-plane ultrasound image by operating the diagnostic seventh and eighth ultrasound transducers 36 and 38 simultaneously or sequentially, and may determine a treatment site based on the bi-plane ultrasound image. After accurately identifying the treatment site, the third probe 30 may stop operating the diagnostic seventh and eighth ultrasound transducers 36 and 38, and may operate the therapeutic sixth ultrasound transducer 32 that treats an affected part, that is, a target for treatment. During the treatment, in order to examine a treatment development, the third probe 30 may stop operating the therapeutic sixth ultrasound transducer 32, and may operate the diagnostic seventh and eighth ultrasound transducers 36 and 38 that monitor a treatment status of the affected part. Thereafter, the third probe 30 may stop operating the diagnostic seventh and eighth ultrasound transducers 36 and 38, and may operate the therapeutic sixth ultrasound transducer 32 again to continue the treatment. By repeating the above-described method, optimal treatment results may be obtained. The above-described operation may be applied to operations of the probes of the other examples.
